Application led March 22, 1923. Serial No. 626,326.

To @ZZ/whom it may concern:

Be it known that I, EPPA H. RYON, a citi- Zen of the 'United States,residing at lNaltham, in the county of Middlesex and State ofMassachusetts, have invented a newl and useful Ttube-Frame Bracket, ofwhich the following is a specification.

This invention relates to an end bracket or support for a tube frame ofthe type used in Axminster carpet looms for inserting the pattern yarntufts between the warp threads.

The present commerical tendency is to greatly increase the width of suchlooms,

with a corresponding increase in the length and width of yarn tubeframes.

It is the general object of my present invention to perfect theconstruction of such tube frames by providing improved end brackets orsupports for detachably connecting the tube frames t0 the transportingrpattern chains.

My improved brackets or supports are secured to the tube frames by aconstruction which is extremely rigid and reliable and which cannotbecome detached or displaced under any reasonable conditions of use.

In the preferred form, this construction involves the use of an endblock fitted within the end of a tube frame and interlocked withportions of the frame and of the bracket so that all of the parts arefirmly and rigidly secured together.

My invention further relates to arrangements and combinations of partswhich will be hereinafter' described and more particularly pointed outin the appended claims.

A preferred form ofthe invention is shown in the drawings in which- Fig.1 is a front elevation of a tube frame embodying my improvements;

Fig. 2 is an end elevation thereof;

Figs. 3 and 4 are detail sectional views, taken along the lines 3-3 and4-4 in Fig. 2, and

Fig. 5 is a perspective View of the separated parts before assembly.

Referring to the drawings, I have shown a plurality of yarn tubes 10mounted on a rectangular' tube frame 11', the tubes being securedthereto by soldering or in any other usual manner. Slits 12 in thebottom and top surfaces of the tube frame ll extend nward from the endskof the tube frame provide tongues or projectionsI 13v and 1-4 whichpreferably extend slightly beyondthe side walls of the tube frame.

vEnd blocks 15 are formed of rigid ma i terial such as die castings,theconstruction,

of the block being clearly shown in- Fig.'v 5.' Grooves or recesses 16are formed on-.the upper and lower ends of the block and the portion 17of the block is of such dimensions as to fit closely within the tubeframe 11. The outer portion 18 of the block is provided with avertically extending groove or recess 19 adapted to receive a bracket orsupport 2O by which each end of the tube frame is attached to thepattern chain.

Springs 21 having hooks 22 at their upper ends are secured to thebrackets 20 by screws 23 and constitute means for detachably securingthe brackets to the chains. A plate 24 is welded or otherwise secured tothe inner side of the bracket 20, the upper end thereof forming a spoolbearing and the lower end being offset at 25 for' a purpose to beexplained.

Having described the details of construction of my improved tube framebracket,-

the method of assembling the parts is clearly indicated in Fig. 4. Theblocks 15 are inserted. in the ends of the tube frame l1 until shoulders26 on the sides of the blocks engage the side walls of the tube frame.`

laI0

15 and the bracket is seated in the recess 19.

The offset lower end 27 of the bracket 2() is then forced upward intothe lower recess 16. completing the assembly of the parts.

From this description it will be apparent that my improved. tube framebrackets are secured to the tube frame without the use of screws, studsor rivets and that the entire process of assembling the parts involvesmerely the bending of the tongues or projections 13, 14 and 27.

While I have described the assembling of the parts as taking place intwo consecutivev steps, it will be evident that the bracket 2O may' beplaced in position on the block 15 before the latter is inserted in thetube .frame ,andi that the projections 13, 14 and 27, may be bent inwardto lock the-'parts to ether at a single operation if so desired.

{aving thus described my invention and the advantages thereof, I do notWish to be limited to the details herein disclosed otherwise thanl asset forth in the claims, but

vwhat I claim is 1. Means to support a tube frame comprising ya blockfitting within the end of c Said tube frame, means to secure said block'y in position, a supporting bracket, and means to secure said bracket tosaid block.

2. Means to support a-tube trarneV comi. prising a'blocktting Within-theend of said 'tube -l'ranie and having recesses to lreceive inwardly`offset portionsof said tube frame which thereby retain said block inposition,

and a supporting bracketrmly secured to said block.

3. Means to support atube frame comprising a 4'block ittingwithinthe endof said tube frame and having recesses to receive inwardly offsetportionsgoi` said tube frame which thereby .retain said bloclcinposition, and a supporting brackethaving portions also seated in saidrecesses which retain said bracket rigidly attachedpto-saidl aixed mysignature.
